Canikon another dinosaur?

I can't for the life of me understand why the mirrorless and m4/3 users are bent on proving that the DSLR is 'dying' or some other camera will 'kill' it. What is this obsession? Some way to prove that those people actually have "the way and the light" or something?

And it seems to me that everyone pushing this 'stuff' has no need of a genuine TTL OVF, has no need of AF tracking or plenty of body controls or a camera they can't 'fit in their pocket'.
